26.7.3_2 Kernel panic - missing init

[Timeraider]

That cant be good.. image speaks for itself XD
Wont be the best strart of the weekend ive had.. not sure how ill fix it yet

[Timeraider]

Ended up having to reinstall.
Guess I learned my lesson to always make an ZFS snapshot no matter how small the update looks

If you're back up and running on 26.7.3 then your hdd may be dying.

Same like thread starter, same issue.

26.7.3_8 killed my system twice -> reinstallation twice.

Update from 26.7.2_x to 26.7.3_8, system got panic. Reinstalled, with 26.7, it runs, update to _8 it's crashing.

Bare metal China Appliance, Intel, two M.2 SSDs as ZFS Mirror, was working for one or two years.

After each restore, I sent a crash report via the WEBGUI. My mail domain (which is my own, so it's unique) is the same as the one used here in the forum, in case you'd like to check it out.

I don't feel like doing a third restore. I'm going to wait for the next update and keep my fingers crossed.

Devs: Thanks for your work! <3

First and foremost, in case of a kernel crash:

- even if on UFS

-even on ZFS - and forgot to take a snapshot


There are always 2 kernels available on the machine. And the one that is crashing is the first/latest one.

When dealing with a kernel crash, assuming everything else including hdd is healthy, No Reinstall is Required.

Booting into the second kernel from the boot menu will suffice.



In this particular case, if people are asking, Franco may be able to provide a 26.7.3-ciss kernel that you may be able to install with

Code Select Expand

OPNsense-update -zkr 26.7.3-ciss then temporarily lock the kernel in the GUI and upgrade everything else to 26.7.3_8

Whether the above happens or not remains to be seen.

In the meantime it is safe to upgrade the packages and reboot.

OPNsense-update -p

Thx, newsense!

I think I understand the basics.

I didn't see a boot menu. I was locally on the machine and ended up at the command line with the "mountfs" prompt, or something like that.

Locking the kernel—that's clear, too.

Unfortunately, I don't know who Franco is. <- forget it. I see.

Erm...I was thinking about this thread when I answered. If that applies to you then what I wrote about a testing kernel still applies.

https://forum.opnsense.org/index.php?topic=52686.0


In this thread in particular the OP might have a hdd failure...that's still unclear.

In short, if you're affected by the ciss issue then the fix will come either in a test kernel or 26.7.4.


OTOH if you find your issue to be different than the one discussed in the thread I mentioned please open a dedicated thread with all the proper details - jumping in other people's threads only muddies the water.

Okay, got it.

I didn't catch where the CISS topic came from, but I'm just an advanced user with a vague, half-baked understanding. I couldn't see any parallels in the other thread.

Your tip to lock the kernel actually helped. I was able to update the system.
But I'm already annoyed with myself for not documenting the whole issue better. I'll document it better for the next update and start my own thread. Thanks for your patience.
